Manually Adding the Tool List

Some older CAD programs separate the tool information into two files. One file contains hole locations, and the other contains the tool size information. We expect the Excellon/NC drill file to be completely self-contained, so we don’t automatically look for a tool list file.

Our site will detect and reject drill files that don’t contain tool size information, so in the case of split files, you shouldn’t be able to accidentally place an order.

Drill Tool Information

Since these files are often “human readable” files, they vary significantly in how they’re presented. Typically, they’re presented in a table format similar to this one.
